RALEIGH, NC, October 17, 2017

Painful post-surgical drains may become unnecessary for breast cancer patients who undergo a mastectomy procedure (removal of the breast).  A level I clinical study seeks to provide evidence that the skin flap can be adhered to the chest wall with TissuGlu Surgical Adhesive® after removal of the breast tissue, assisting the healing process and eliminating the need for drains. A drain-free recovery could help to make the experience easier for both mastectomy patients and their care providers.

The European study, with 4 centers in Germany and 7 in the UK, started in February and has completed enrollment of nearly 80 patients, with half of the patients treated with post-surgical drains and the other half treated with TissuGlu and no drains. After a 90 day follow up period, the study will assess the number of clinical interventions related to wound healing and fluid management in both groups. Preliminary assessments indicate that the outcomes of the study are positive.

“Our patients have been very enthusiastic about participating in the study when they hear about the chance of a drain-free procedure,” says Ms. Polly King, Principal Investigator at the Royal Cornwall hospital in the UK, which recruited the highest number of patients for the study. “Patients without drains feel more comfortable about going home sooner than those who wake up from surgery with a drain.”

“TissuGlu has been used for flap fixation after mastectomy and several other ‘flap procedures’ in Europe for a few years now. The body of evidence required to bring this new approach into the mainstream has been steadily growing, and this multinational prospective randomized study really represents the ‘Gold Standard’ of clinical evidence,” says Mart Pearson, VP Europe for Cohera Medical, Inc. “We hope that these results will open the door for many other breast cancer patients who would greatly prefer a recovery without drains.”

This study adds to the growing body of evidence of positive TissuGlu outcomes.
